Description

The utility model relates to construction machines used in the planning of the earth's surface, for example, in the construction of roads and railways, runways of airfields, the layout of rice checks, fields for cotton and other objects.

Known domestic and foreign automated field planners [1], [2], [3], [4], [6], widely used in reclamation construction, as well as a profiler-distributor with automatic control for the construction of road foundations [5].

In these planners and profilers, carbonless self-propelled guns are used, which have significant advantages over copier ones (see [5], [6]). To obtain an acceptable evenness of the subgrade, multiple passes of the machine through the same place are required. For the best cars - 2-3 times, usually 7-8 times.

All the automated planners (profilers) known to us perform leveling of the subgrade, moving only in one direction - usually forward. Therefore, for effective alignment in the opposite direction, they must be rotated 180 °, which is very difficult, especially when building linear objects, such as roads and railways, runways and others. U-turn is hindered by the approximate equality of the width of the subgrade and the physical length of the base of the scheduler (profiler). For example, for long-base trailed planners, the smallest turning radius in the working position is from 10 to 16 m. Similar difficulties arise in the planning of rectangular areas, especially in the construction of rice fields, the area of which is usually small, so that significant surfaces in corners remain uncultivated during a turn. .

The purpose of the invention is, while maintaining the advantages of the above-mentioned planners and profilers, to make it possible for them to work in a shuttle way (forward-backward-forward, etc.) without the need for a 180 degree turn.

Figure 1 shows the automated reversible shaper in the working position (forward movement), side view, figure 2 is the same, the reverse movement is reverse; figure 3 is the same in plan; figure 4 - profiler reversible in transport position: the working frame is raised, the working body is located along the longitudinal axis of the profiler.

Shown in figures 1, 2 and 3, the profiler contains a frame consisting of a front 1, a back 2 half-frames, between which there is a working half-frame 3, on which a working body 5 is fixed with an arm 4. The working body (hereinafter - RO) may be a dump (such as a grader) or a screw distributor of a known type (not shown in the figure).

Work frame 3 is connected to the front 1 and back 2 frames by means of symmetrical parallelogram mechanisms. Each of the mechanisms contains a traction earring 6, a lifting hydraulic cylinder PO 7 and a hydraulic cylinder 8 for changing the angular position of the front and rear half frames.

The bracket 4 is connected to the working frame 3 by means of a slewing ring 9, providing reversal of the PO at any given angle to the direction of movement of the profiler.

The effective work of the reverse profiler in planning the machined surface, as in the prototype, is carried out with the participation of an automatic control system. So on the half frames 1 and 2, pendulum noise-proof angle meters 10 and 11 are installed to control the angular position of the corresponding half frame in order to obtain the greatest evenness of the planned surface.

When the profiler moves “forward” (FIG. 1), the angle gauge 11 located on the rear frame 2 controls the hydraulic cylinder connecting the rear frame with the working frame and changes the angular position of the rear frame, and when reversing (FIG. 2) - the movement “back” - the working body is rotated 180 degrees, and the angle meter 10, located on the front frame 1, controls the hydraulic cylinder connecting the front frame with the working frame and changing the angular position of the front frame.

The profiler also contains a power module with a driver's cab 12 (such as a grader), front 13 and rear 14 wheel supports.

In the proposed profiler, a design with symmetrical parallelogram mechanisms allows for moving the working body to the transport position (Fig. 4) to raise the working body with lifting cylinders and deploy it along the longitudinal axis of the machine, while reducing the dimensions and increasing the clearance of the machine during transportation and movement on roads.

The proposed utility model can significantly increase the efficiency and quality of work of motor grader type construction building machines used in the planning of the earth's surface, for example, in the construction of roads and railways, runways of airfields, the layout of rice fields, cotton fields and other objects.
